METHOD FOR USE IN SOAP-POWDER MAKING. I

Application fi led March 22, man Serial No. 454,431.

To all whom it may concern:

Be it known that I, Jonson A. DE Cnw, a citizen of Dominion of Canada, residing at Mount Vernon, in the county of Westchester and State of New York, have invented certain new and useful Improvements in Methods for Use in Soap-Powder Making, of which the following is a specification.

This invention relates to certain steps in and apparatus for use in the manufacture of soap powder, especially in that type wherein;

a mixture of soap andsoda ash is atomized into a hot chamber. i The object of the invention is to so intimately and smoothly mix the soap and soda ash or other alkali that the mixture does not jell or become lumpy and thereby clog the atomizer if not making atomization impossible. I

This object is obtained by heating the soap and alkali such as soda, in liquid form separately under pressure, forcing fine streams of soap and soda to impact against each other preferably while at a temperature approximately 180 F., whereupon an intimate, uniform, smooth and exact mixture of the soap and alkali that will not jell results in a, minimum of time.

To this end I have devised an apparatus for carrying out the invention, one embodiment of which is herein described, it being understood however, that it is to be taken in an illustrative sense and not a limiting one.

. -This embodiment is shown diagrammatically in the accompanying drawings in which- Figure 1 is an elevation showin the arrangement of the various unitso the apparatus;

Fig. 2 shows an additional blending device which I may use in connection with the apparatus of Fig. 1. s

Figure 3 shows one of the perforated plates 22.

In the drawings, a tank 11 will be seen in which hot soap 12 is adapted to be placed under pressure. Steam coils 13 or their equivalents may be used to maintain the soap at any desired temperature indicated on the thermometer 14 and the degree of pres sure under which the soap is maintained is shown by the gauge 15.

A similar tank and associated parts, 11',

13', 14: and 15' is provided for liquid soda 16 or other alkali.

Conduits or pipes 17 and 18 lead from tanks 11 and 11 respectively toa'mixing' I chamber 19 equipped with a thermometer 20. Adjacent the ends of this mixing chamber I provide screens or perforated plates 21 and.

22 whereby the soap issuing from the pipe 17 and the soda issuing from the pipe 18 re- 1 spectively are broken up into fine streams.

As the two sets of streams made bythe perforated plates 21 and '22 are oppositely directed, they impact against each other and an intimatemixture results, especially if the temperature of the mixing chamber is 25 are shown in dotted lines because they form no part of this invention. In the hot chamber 25, the soap powder is formed and falls to the bottom of the chamber where it is collected. V

The screens or perforated plates 21 and 22 or any other equivalent means for breakin the liquids up into fine streams, are provide; with apertures or openings, the area of which maybe varied to suit the relative proportion of the materials it is desired use.

11 the event that further mixing is desired, a further screen or screens (or other perforated means) may be used as at 26 and 27 to more thoroughly and intimately mix the two liquids. Also the apertures in these plates may be varied asto size to make a finer or more complete mixture.

This form of apparatus is very efiective in carrying out the method involved in this invention and it produces such a thorough, intimate and non-jellying mixture of the soap and the sbda that the troubles heretofore experienced in atomizing a mixture of such ingredients, are completely overcome.

These troubles have been so serious that soap liquid soda to impact against each other 10 plants in general have hesitated to go into through orifices and forcing the hot mixture the manufacture of soap powder, so this inthrough a further atomizing device to furi'ention apparently will now render possible ther sub-divide. commingle and mix the soap :1 wide adoption of soap powder making. and soda into an intimate non-jell x 'ing mixlVhat I claim is: ture. 15 A method for use in soap powder making In testimony whereof I have affixed my which consists in heating soap and liquid signature to this specification.
